GAYLORD V. BARNES. OF SAN RAFAEL, CALIFORNIA 1 '0 all 'whom' it midi/concern."

State of California, have invented a new and useful Shock-Absorbing Device for Vehicles, of which the following is a specification in such full and clear terms as will enable those skilledin the art to construct and use the same.

This invention relates to a shock absorbing to be especially adapted toearry a load in compression, it is very liable to' breakage when expanded unduly as" happens with a rapidly drive-n automobile when a chuck hole is struck. It, therefore, becomes necessary to provide some auxiliary means for protecting the leaf spring from 'brealv'age upon undue upward movements of'the vehicle body. Such means must permita certain movement of the body, however, in order to prevent undue shocks to the occupants as well as injuries to other parts of the machine, and these objects are sought to be obtained in the invention here dis closed.

in the drawings in which thesame numeral of'reference is applied to tlie'salne portion throughout. the several views. Figure l is a rear elevation. partly in section. ol' a por tion of the supporting axle of a vehicle. the. spring for carrying the. same. one side t'rame of the body and the device t'or preventing injury to the springs. Fig. '2 is-a side elevation of the shock absorbing device and the spring to whiclrit is attached, Fig. 23 is a plan view of the device as shown in Fig. 1, and- Fig. l is a side elevation of the bracket-to which the shock absorbing spring is secured, showing the same applied to the side frame of the vehicle.

The numeral 1 represents the axle of a vehicle, 2 the lower portion of a so called full elliptic spring and 3 the upper port ion thereof. The spring is suitably secured to the. axle by means of a clip l and the frame of the vehicle is suitably supported therefrom by means of a bracket 5, said bracket having bolts (3 and 'I to secure the same to Specification of Letters Patent.

7 v Q the upper limb of the sprim'.v T-he bracket Be it lnm\vn tl at I, Gavnonn V. Banmzs,

a citizen of'the United States. residing at San Rafael, 1n the county of Mann and 5 is provided with a curved seat at smut with an upstanding slottedplate at 9. Theusnal channel frame is shown at 10 and is 60 supported on the top of the spring by ineans of a' heavy bolt It. said bolt also serving to Sttflllt! a slotted L shaped bracket 12 on the inner side of the channel sid'e rail 1t). In order to easily place'the bracket 12in 5 position, it is'provided' with an open slot so that it makes little ditterencewhere the bolt 11 is positioned. A horiz )ntal limb on the bracket 12 supports a cap 13, said cap being rigidly secured thereto by means of a boltlt. having nuts 15 and 16 applied thereto. The cap 13 supports the lower part of a heavy spiral spring 17 while an oppositely placed cap 18 is placed on-the top of said spring. Also passing through the spiral spring are two rods 19 and '20, which are formed into a loop 21. at the lowerends thereof, nuts 22 securing them to the upper cap 18. ,The loop 21 is large enough also; insertion therethrongh of a suitable heavy strap 23. said straphavingQa buckle 24 and loop 25 for the free endltliereof.

In operation the spring is loaded with a normal load and the strap 23 is buckled tight around the axle. The vehicle is then ready 86 to be used and since tbe spring clip cannotlit't the spring until it has moved to the top of the slot, there is prmrtically no danger of breaking the elliptic spring. since by the time'the frame support reaches the top of 90 said slot the spiral springavill be under.

such heavy compression that practically no damage can be done the elliptic spring.

Having thus described my invention wlizlt l claim as new and desire to secure by I. $6 ters latentof the llnited'states. is as fttl lows: I a

t. In a shock absorbing device for vehicles, an axle. a spring supported thereby, a. vellielc frame supported upon said spring and free to move upwardly from the spring a short distance, a spiral spring supported on the vehicle frame, and means connecting Zlltl spiral spring and said axle to prevent the vehicle frame from rising more than a tixed amount, substantially as described.

2. in a short; absorbing device for vehicles. an axle. a spring supported thereby. a vehicle frame supported. upon 'said, l'itl 11 and l'ree to move about the spring-a l|u|'t 11(i distance. a bracket secured to said vehicle frame aml'carrying a spiral spring. a yoke frame and a; strap connecting said spiral spring and the axle to prevent the vehicle frame from rising more than a fixed amount, 15 substantially as described. I

In testimony whereof I have hereunto set my hand this 2d day of November A. D. 1911, in the presence of the two subscribed bearing upon'the upper-end of said spiral I spring and a strap passing through said yoke and under the axle to prevent the \e hicle frame .frorir moving upwardly more than a fixed amount, substantially as de-. scribed. 1 I 3.,In a shock absorbing device for vehicls, an axle, a spring supported thereby, a witnesses. slotted cli secured to the top of said spring, GAYLORD V.
